'They Are Billions' for PC is a deep strategy game that finally makes you fear zombies

It's tough to come across a good zombie game after so many terrible efforts. Thankfully, They Are Billions is a solid zombie title.
They Are Billions is aptly named as they really are in the billions, and it's on you to survive. In a game about building up a steampunk settlement and fending off hordes of undead, I've failed more times than I can remember, and I'm okay with it. This is a title that's currently in Early Access and as such should be taken as a work in progress. Things may change and any faults I highlight here may be addressed in future versions.
In its current state, They Are Billions is worth checking out for zombie fans.
